Question

Sheet Metal Flat State Calculation difference between PRO-E & Inventor.

Hello ,

I would like to know how any of you have managed a transitition from Autocad Inventor to PRO-E for sheet metal components, especially for flat state.

Current Scenario in my organiztion : Inventor is used for developing sheet metal drawings. The Flat state dimensions for Sheet metal component is also given in the same drawing. This is done by inputting the k-factor values as per sheet thickness and material.

After migration to PRO-E , for the same sheet metal component , after inputting the same k-factor value , we have a difference in the flat state value of the sheet metal component.

This could have an impact on the sheet metal component during manufacturing.

Why does PRO-E and Inventor throw up different flat state values for the same k-factor , thickness and Material?

Has anyone come across a similar scenario?

If u site an example we might help you, however u can manually calculate for one sample case the developement length and can decide which software is giving correct development length,

Please find attached an example. A sheet metal part of dimensions 30*60*2. I have attached flat state views of both inventor and PRO-E for reference.

The flat state length generated in Inventor is 86.5 and 83.39 in PRO-E . (Dimensions in "MM")

Please find a screenshot attached.PRO-E+VS+INVENTOR.JPG

Shibin,

I can see different value on the picture...

Inventor is 86.5 and ProE is 86.39 mm ... the difference is 0.11 mm
